LF/LF/LF/LF/LF/LF/LF JFET Input Operational Amplifiers. General Description. These are the first monolithic JFET input operational. 1 Nov LF (AV=5). • High Impedance Buffers. Extremely fast. 4. μs settling time to %. • Wideband, Low Noise, Low Drift Amplifiers. These are the first monolithic JFET input operational amplifiers to incorporate well matched, high voltage JFETs on the same chip with standard bipolar.

Here is the circuit: Your name or email address: Simple Question about Current Posted by paul in forum: It’s been a while since I’ve messed around with this part, so I don’t remember the output voltage range.

Great specs and a drop in replacement for the Post as a guest Name. Is this how this old opamp is supposed to operate? Home Questions Tags Users Unanswered. What country are you in? Use a rail-to-rail amplifier. The configuration shown doesn’t give a gain of 4. In any case though you’ll want to check your input voltage to see if it always falls within the input common mode range of the op amp being used.
So, is this op-amp is to repair your scope?
I’m curious – what lf36 it about your circuit that makes you think a JFET input stage can’t “handle it”? These two op-amps are much higher speed op-amps than the and require a lot of Jan 2, If you don’t need any of the more extreme performance parameters rail to rail input or output, ultra low noise, ultra wide bandwidth, etc. Oct 9, 2.
BrianDrummond – good spot! Assuming it can swing within 2 volts of Vcc, then yes, it should work as simulated. However, I noticed that. Is there any “standard” modern rail to rail opamp with GBP around 5Mhz you could recommend?
Simple question about capacitor Posted by Bamerni in forum: I have a box of LFs. Simple question about solenoids Yes, a TL would llf356 a reasonable replacement.

So after making the lv356all the opamps on the scope PCB were working fine. Jul 1, 4. Posted by Calcifer in forum: Jun 17, 5, 1, Nov 13, 4 0. They are in stock at Digi-Key and there are Ebay sellers all over the world. Jul 4, It won’t at all properly work on a single 3.

The FET op amps often have a very narrow input range which is not good enough unless the supply voltages are the full plus and minus 15, but you seem to have plus and minus 12 which isnt too bad as long as the input does not get closer than about 4v to either rail.

Simple question about LF Reply to Thread. Jul 2, 9. Guess repairing this scope is impossible. I suggest that you consider the LF
